Русско-англо-русский юридический словарь

Sharia law is Islam’s legal system, acting as both the fundamental religious moral code of Islam and holistic rules that apply to all areas of life, including religious obligations, daily routines and personal beliefs.

It principally relies upon teachings from the Quran and the Sunna – the saying, teachings and practices of the Prophet Mohammed, but also draws from Ijma’a, the consensus of Muslim scholars, and Qiyas, reasoning through analogy. (inews.co.uk)
